The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

What happens when you combine 6.022 times 10 to the 23 piles of dirt into one? You make a mountain out of a mole hill. Scholars use dehydration to obtain percent composition and then calculate the molarity of the original...

Challenge scholars to research a biome and create a presentation for the producers of Survivor to choose their ecosystem for the next season's show. The materials include outlines, worksheets, and grading rubrics for individuals as well...

Students discover how the coefficient of restitution is applied to sports by measuring the bounciness of a ball. After examining the mathematical equation that applies to coefficient of restitution, students go to the gym, measure the...

Students identify the five major alternative energy sources. For this physical science lesson, students assess the advantages and disadvantages for each type of energy. They complete a concept map using information they researched.

Students collect and analyze variable data and understand the concept of electrical power.  In this energy instructional activity students use a spreadsheet to manage their data and create box plots. 

High schoolers examine the definitions of biomas gasification and generate their own biomass gas.  In this renewable energy lesson students collect gases and roast a marshmallow. 

Students explore alternative energy sources. In this wind energy lesson, students will investigate the difference in the speed and smoothness of wind at different altitudes above earth. Students will use kites, helium balloons,...

Second graders explain the relationship between energy and work. In this technology lesson plan, 2nd graders describe the different uses of machines in their everyday lives. They record observations and data in their science journal.

Examine water pollution and legislation through this reading comprehension activity, intended to correspond with a specific text but valuable even without it. Learners read 10 sentences, unscrambling the bold word to complete each (i.e....

Beginning with a general discussion about natural gas, methane, and hydrocarbons, a few videos and diagrams are projected to support the lecture. Individuals participate in a brief activity by drinking juice through a straw, and then...

You are what you eat—or at least a part of what you eat. Budding scientists examine owl pellets to develop their own food webs. They use tooth and skull identification techniques to classify what they find.

Radioactive isotopes have a wealth of uses, but their waste may cause some concern. One of four free-response questions challenges learners to devise a waste removal strategy for medical radioactive substances. Other questions address...

The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.

Use this slide show to introduce your class to some of our most useful natural resources. The text beneath the photographs differentiates between renewable and non-renewable resources. The need for conservation of resources and human...

Here's a handy two-part learning exercise that uses an article about plants to assess reading comprehension. After reading the passage, kids answer questions based on the information in the text.

Students write a report about energy use. For this conservation lesson, students interview adults about their use of renewable and nonrenewable energy. Students synthesize this information and write a report from the point of view of a...

Students show that energy is conserved in the laboratory. They calculate the work done by a force on an object as the product of the force and a displacement of the object from a reference point.

Fifth graders investigate situations that show how kinetic and potential energy are exchanged. They determine how friction is a source of energy transfer from kinetic to thermal energy by experimenting with a car and track. They answer...

High schoolers recognize the benefits of ethanol and study photosynthesis.  For this ethanol lesson students complete an experiment that shows the procedure that starch can be hydrolyzed by salivary amylase. 

Students explore the properties of electricity. This lab shows students the need for a circuit in order to have a flow of electricity. It demonstrates Ohm's law, which relates voltage, current, and resistance.

Students explore how to build an efficient windmill design by taking into account how the lift and drag caused by the movement of wind can be used to make the blades of the turbine move. Through their readings, hypothesis and by trail...

Students participate in three stations in which they are made aware of the environment, ways to preserve it, the importance of preserving it and their part in preserving it. They discuss where items are found, recycling, and...

Students research and compare two products that provide the same function but require different amounts of energy to do the job. They examine and demonstrate energy efficiency and discover how it applies to different technologies and...
